如何显示我的自定义帖子类型的类别？

我有一个自定义的帖子类型。我想做的是在项目顶部显示项目类别，以便访问者可以相应地筛选项目。

在我的functions.php 我有：

<?php

require_once(\'portfolio-type.php\');
add_filter(\'excerpt_length\', \'my_excerpt_length\');

function my_excerpt_length($length) {
return 25; 
}

add_filter(\'excerpt_more\', \'new_excerpt_more\');  
function new_excerpt_more($text){  

return \' \';  
}  

function portfolio_thumbnail_url($pid){
$image_id = get_post_thumbnail_id($pid);  
$image_url = wp_get_attachment_image_src($image_id,\'screen-shot\');  
return  $image_url[0];  
}
?>

在中portfolio-type.php:

 <?php

 if ( function_exists( \'add_theme_support\' ) ) { 
add_theme_support( \'post-thumbnails\' );
set_post_thumbnail_size( 270, 170, true ); // Normal post thumbnails
add_image_size( \'screen-shot\', 720, 540 ); // Full size screen
 }

 add_action(\'init\', \'portfolio_register\');  

 function portfolio_register() {  
 $args = array(  
    \'label\' => __(\'Portfolio\'),  
    \'singular_label\' => __(\'Project\'),  
    \'public\' => true,  
    \'show_ui\' => true,  
    \'capability_type\' => \'post\',  
    \'hierarchical\' => false,  
    \'rewrite\' => true,  
    \'supports\' => array(\'title\', \'editor\', \'thumbnail\')  
   );  

register_post_type( \'portfolio\' , $args );  
 }  

register_taxonomy("project-type", array("portfolio"), array("hierarchical"  =>  true, "label" => "Project Types", "singular_label" => "Project Type",   "rewrite" => true));
 ?>

最后在我的索引中。php我有：

<!-- Start Projects -->

                    <div id="posts" class="row isotope">

                      <?php if (have_posts()) : while (have_posts()) : the_post(); ?>  

                          <?php  
                              $title= str_ireplace(\'"\', \'\', trim(get_the_title()));  
                              $desc= str_ireplace(\'"\', \'\', trim(get_the_content()));  
                          ?>     

                          <div class="item post item span4 isotope-item">

                            <a class="project-wrp fancybox" title="<?=$title?>" rel="lightbox[work]" href="<?php print portfolio_thumbnail_url($post->ID) ?>"><div class="profile-photo"><div class="profile-icon">&#0102;</div><?php the_post_thumbnail(array(\'230\',\'170\'),array(\'alt\' => \'\')); ?> </div>  
                            <div class="project-name"><?php echo $title; ?></div>
                            <div class="project-client"><?php echo $desc; ?></div>
                            </a>
                          </div>  
                      <?php endwhile; endif; ?>  


                    </div>

function portfolio_register() { $labels = array( \'name\' => _x(\'Portfolio\', \'post type general name\'), \'singular_name\' => _x(\'Portfolio Item\', \'post type singular name\'), \'add_new\' => _x(\'Add New\', \'portfolio item\'), \'add_new_item\' => __(\'Add New Portfolio Item\'), \'edit_item\' => __(\'Edit Portfolio Item\'), \'new_item\' => __(\'New Portfolio Item\'), \'view_item\' => __(\'View Portfolio Item\'), \'search_items\' => __(\'Search Portfolio Items\'), \'not_found\' => __(\'Nothing found\'), \'not_found_in_trash\' => __(\'Nothing found in Trash\'), \'parent_item_colon\' => \'\' ); $args = array( \'labels\' => $labels, \'public\' => true, \'publicly_queryable\' => true, \'show_ui\' => true, \'query_var\' => true, \'rewrite\' => true, \'capability_type\' => \'post\', \'hierarchical\' => false, \'menu_position\' => 8, \'supports\' => array(\'title\',\'editor\',\'thumbnail\') ); register_post_type( \'portfolio\' , $args ); } add_action(\'init\', \'portfolio_register\');

function create_portfolio_taxonomies() { $labels = array( \'name\' => _x( \'Categories\', \'taxonomy general name\' ), \'singular_name\' => _x( \'Category\', \'taxonomy singular name\' ), \'search_items\' => __( \'Search Categories\' ), \'all_items\' => __( \'All Categories\' ), \'parent_item\' => __( \'Parent Category\' ), \'parent_item_colon\' => __( \'Parent Category:\' ), \'edit_item\' => __( \'Edit Category\' ), \'update_item\' => __( \'Update Category\' ), \'add_new_item\' => __( \'Add New Category\' ), \'new_item_name\' => __( \'New Category Name\' ), \'menu_name\' => __( \'Categories\' ), ); $args = array( \'hierarchical\' => true, // Set this to \'false\' for non-hierarchical taxonomy (like tags) \'labels\' => $labels, \'show_ui\' => true, \'show_admin_column\' => true, \'query_var\' => true, \'rewrite\' => array( \'slug\' => \'categories\' ), ); register_taxonomy( \'portfolio_categories\', array( \'portfolio\' ), $args ); } add_action( \'init\', \'create_portfolio_taxonomies\', 0 );

<?php $taxonomy = \'portfolio_categories\'; $terms = get_terms($taxonomy); // Get all terms of a taxonomy if ( $terms && !is_wp_error( $terms ) ) : ?> <ul> <?php foreach ( $terms as $term ) { ?> <li><a href="<?php echo get_term_link($term->slug, $taxonomy); ?>"><?php echo $term->name; ?></a></li> <?php } ?> </ul> <?php endif;?> ?>

$term_args = array( \'post_type\' => \'portfolio\', \'taxonomy\' => \'project-type\', \'hide_empty\' => true, \'fields\' => \'all\' ); $term_query = new WP_Term_Query( $term_args );
